Southern Marsh Orchid problems — and how to fix them
Southern Marsh Orchid (Dactylorhiza praetermissa) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Drying out in summer
Unlike heathland orchids, this species cannot tolerate drought; a dry summer causes the tubers to shrink and fail to produce a flowering spike the following year — mulch the surrounding area with grass clippings to retain moisture.
Interspecific hybridisation
In gardens where D. fuchsii also grows, the two species hybridise freely, producing intermediate plants — lovely but they can gradually dominate and displace the parent species over several generations.
